I have a strange problem with my player and my sandisk sdhc 8gb card. Starting the player, it shows the "search d2 ext" msg, does some processing and then moves on to the main menu...so far so good. Now, when I'm trying to browse the card through "folders" the player just hangs...firmware is pretty new (2.57)...updating is always good but something tells me it won't solve the problem and may I say, that prior to writing this thread I've tried empting the sd card, format it full format (fat 32), refilled it, and the problem remained. I would appreciate a fast response as I'm in the middle of a trip and I'm constantly moving..
